Planning
Indications
Main risk factors are:
- Hypocoagulability, such as anticoagulant medication
- Trauma
Choice of modality
- Ultrasonography of muscular hematoma is generally the initial choice in younger patients to confirm a strongly suspected hematoma.
- CT of muscular hematoma is generally the initial choice in acute abdominal pain.
- In suspected bone fracture, X-ray of fractures is generally the initial choice.
IV contrast
For follow-up of a known muscular hematoma, it is sufficient to perform CT without IV contrast.[notes 2] If detection of contrast extravasation or active bleeding is specifically requested, an arterial phase contrast CT is preferred.[1]
Evaluation
- Location
- Size
- If contrast CT, any visible contrast leakage

- ↑ A contrast CT can detect extravasation of contrast material, but this does not seem to be correlated to clinical severity, as evidenced from rectus sheath and iliopsoas hematomas.
